Youkilis is active but not available, so Boston demoted right-hander Junichi Tazawa to Triple-A to make room on the roster for Iglesias.

Nick Punto has been filling in for Youkilis at third base, so manager Bobby Valentine could decide to shift Mike Aviles to the hot corner instead and use the slick-fielding Iglesias at shortstop. Or maybe Iglesias will just hang around for a few days as bench insurance.

Valentine was full of praise for Iglesias during spring training, but the 22-year-old was hitting just .200 with a .485 OPS at Triple-A after posting similarly underwhelming numbers in Pawtucket last season. His defense is widely considered Gold Glove-caliber, but so far his bat hasn’t even been utility man-caliber.
